Key Facts

Overview

15471 (1999 BE5) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1999 BE5 as potentially hazardous because its orbit does not bring it close to Earth.

1999 BE5 orbits the sun every 1,520 days (4.16 years), coming as close as 2.38 AU and reaching as far as 2.79 AU from the sun. Based on its brightness and the way it reflects light, 1999 BE5 is probably between 4.042 to 9.037 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of 1999 BE5 has been observed. It completes a rotation on its axis every 112.63 hours.

No Close Approaches

1999 BE5's orbit is 1.42 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1999 BE5's orbit is determined by observations dating back to Nov. 16, 1976. It was last officially observed on Dec. 22, 2022. The IAU Minor Planet Center records 2,799 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
